Symptoms of mite bites on the back

Symptoms of mite bites on the back are mainly characterized by various local skin discomfort reactions. Specific symptoms include: 1. **Itching**: Patients often experience intense itching at the bite site, which may worsen at night and tends to be persistent. 2. **Rash**: The bitten area may develop red papules, papulovesicles, or wheals, often with a central hemorrhagic point caused by the bite. The rash may not be limited to the bite site and can spread systemically. 3. **Edema**: The affected area may exhibit erythematous swelling with noticeable skin edema. 4. **Systemic symptoms**: In severe cases, patients may experience systemic symptoms such as fever, headache, fatigue, shortness of breath, and diarrhea. These symptoms indicate that the mite bite has triggered a systemic allergic reaction or infection.
